Residual Stress

Residual stress measurement is a way to determine if your critical components can withstand the load and stress conditions of operations.

Lambda has extensive experience in testing all types of materials, including metallics, ceramics, and polymers of nearly any shape and size.

We can test components in our laboratory or in the field. All stress measurements are performed by our certified residual stress engineers and technicians. Lambda does not subcontract this type of testing to a third party.

With more than half a million completed measurements, over 100 technical papers published, and authorship of the American Society for Metals “X-ray Diffraction Residual Stress Techniques,” Lambda is a recognized leader in this field.

Residual Stress

Testing Services

  • X-ray diffraction – for high resolution measurement of surface and subsurface residual stress in any polycrystalline test part.
  • Ring-core – used to measure principal residual stresses incrementally with depth and can be used on metals, ceramics, and polymers.
  • Hole-drill – used to measure principal residual stresses incrementally with depth and is performed per ASTM E837 specification.
  • Slotting – used to measure residual stress in one direction incrementally with depth.
  • Deep hole-drilling – a technique that can measure residual stresses incrementally very deep into a part beyond the capabilities of typical mechanical methods.
  • Tube splitting – a technique used to estimate the hoop residual stress in thin-walled tubing and performed per ASTM E1928.
  • Sectioning – used for measuring bulk residual stresses in components and useful when incremental residual stress distributions are not required.
